How many partitions can a drive have

Perhaps you want to run Linux alongside Windows, but your computer can't handle a virtual machine. You can create a new drive partition for Linux without touching your existing Windows system.

Alternatively, you could install an older version of Windows on a separate partition for backwards compatibility purposes. Another multi-platform use for partitioning is to work with multiple file systems. While you won't need to do this with your internal drive, it can make external drives more useful if you use them with multiple OSes. Making one partition FAT32 or exFAT would work with pretty much any platform, while you could still keep a separate Mac-friendly file system on another partition.

On the flipside, there are several reasons you should avoid partitioning your hard drive. Here are a few of them. If you're not careful, having multiple partitions could lead to a data loss disaster. While Windows shows separate entries for each partition you've created, those partitions are all still on the same physical drive.

Because of this, if your hard drive fails, is destroyed by a natural disaster, or otherwise stops working, you'll lose everything on it. This could be a shock for a new user, who's used to every drive in the This PC window representing a separate physical device. Thus, backing up your data in Windows , no matter what partition it's on, is crucial. You need to have multiple copies of data for a proper backup. One of the biggest hassles when you have several partitions is keeping them straight.

With any more than three or four partitions, you'll likely lose the organization benefits just trying to keep track of them.

And even with an extra partition or two, you'll still have to set up Windows to save your files and software on the other partitions. This is more complex than saving everything on one partition, making it unnecessary for most people. Additionally, the complexity of having multiple partitions introduces more chances for a mistake.

When formatting one partition, you might accidentally erase another. With one disk partition, you don't have to worry about overall disk space, aside from filling up the drive completely. But with multiple partitions, you can end up in a situation where you're cramped for space on one partition but have plenty of free space on another.

The limited space also means you could run into surprises. For instance, a major update to Windows 10 could require more space than you have free on its partition.

You'd then have to remove some games from a separate partition, shrink that partition, then extend the one with Windows installed. Thankfully, Windows makes it pretty easy to shrink and extend partitions, so you're not locked into your initial sizes. But resizing partitions frequently is inconvenient. Many power users like to partition for the reasons listed above, which is great.

But for the average user, it's often not necessary. Typical computer users don't typically have enough files that they need a different partition to manage them. And they don't often install other operating systems, negating that benefit. While partitioning isn't overly complex, it also introduces some potential for issues for a novice user.
